I am playing as Axis and have reached may 1942. I was about to restart my offensive under the new 1.06.13 patch and after 2 turns of renewed joy I observe that my 2 German Armies (4th Pz and 6th) get reassigned every turn from Army Group A to Army Group B. Hun and Ita Armies stay in Army Group A and don´t get reassigned.

Obvously Army Group B gets crowded, so I tried to reassign again into A, a whooping 50PP - only to see the same thing happening again the next turn.

thank you for your help. I have attached the save for the Axis turn April 30th 1042, the last turn where the 4th Pz and the 6th Armies are still attached to Army Group A. The next turn in May the auto-reassigning occurs.
